6 Claims. `(Cl. 155-88) This invention relates `to improvements in chairs and itconsists ofthe mattershereinafter described and more particularly pointed out in the appended claims.

The chair` with which Ithe invention is more especially concerned is of the oflice type and includes the usual back rest and seat and a pair of supporting legs at each side of the seat, thel legs of each pair being connected together and tothe like leg of the other pair of legs. One of theobjects of the present invention is to .providea chair of this `kind whichis of a simple, light weight, strong and' substantially an all-wood construction, -so that the metallic parts employed in thegchair are reduced to a minimum. Another object of the invention is to provide a chair of this kind wherein the seat may be easily adjusted vertically with respect to the legs so as to be positioned at that elevation best adapted for the occupant. i I A further object of the invention is to provide a chair of this kind `whereinthe seat may also be easily adjusted forwardly or rearwardly with respect to the legs at any elevation of lsaid seat.

The above mentioned objects of the invention, as well as others, together with the advantages thereof will more `fully appearas the specificationproceeds. i

In the drawing: A Fig. 1 is a front to rear, vertical sectional `view the ainner face of the top end portion of each leg is secured an upright guide strip I4 likewise of wood, with its guiding edge disposed about midthrough a chair embodying the preferred form ofthe invention p Fig. 2 is a transverse vertical sectionall view through the seat portion of` thechair as taken on the line 2- 2 of Fig. `1. I

Fig. 3` is a horizontal sectional view through the chair as taken on the line 3-3 of Fig. 2.

Fig. 4 is a perspectiveview of a se'at supporting member embodied in the chair and which will be more fully referred tollater.

Referring nowin detail to `that embodiment of the invention illustrated in the drawing, I0 indicates the base of the chairas a whole and which comprises laterallyspaced pairs of front andrear legs II and I2 respectively, preferably made of wood. The top end `portions of the legs in each pair are vertically disposed and are spaced closer together than the bottom end portions which are curved as best shownlin Fig. l` toprovide a spread for the legs that insures a firm stable base, which will not easily tip over.` y l The top end portions of thelegs in each pair are connected together by a filler 0r web I3 of wood and the inner face thereof is flush with the inner faces of the legs of the associated pair. On

way between the front and rearfaces of the associatedleg. Each leg of one pair of; legs is connected to `theilike leg of the other pairby a wooden cross bar or rung l5. `In each margin of each ller or web is a vertical rowrof holes I6 as indicated in `dotted lines in Fig. 2, the purpose `of which will appear later. i

Associated with the `top end portions of the pairs of legs is a seat supporting element, which bestappears in Fig. 4. It comprises a wooden panel I1 of an area approximating that `of the top end portions of the front `and rear legsof l both pairs. Spaced inwardly from the side edges of said element and depending fromthe bottom surface thereof is a guide member I8 of `a width to fit snugly at its front and rear edges with the opposed guide faces ofthe strips I4 on each pair of legs; Each guide member has vertical rows of holes I9 therein adapted to register with the holes I6 in the filler or web of the associated pair of legs. Inwardly from the guide members I8, the

`panel is provided with slots 20 which` extend par.-

allel with said guide members.`

The chair also embodies abackrest 2| oper.- atively attached to the upper end of a pair of laterally spaced supporting members 22 and hav- Ving horizontal -lower ends that engage both the bottom surface of the panel I1 `andtheinner faces of the guides I8.` Preferably, saidsupporting members are made of wood and their hori- .zontal lower ends are secured to the guides IB by means of bolts 23. p l

The chair further embodies a seat 24 which includes a generally rectangular wooden frame or rim 25 and an upholstery supporting base 25 and secured to the underside of said base and extending from the frontto the rear thereof `are strips 2l. The rim orframe, base and strips just mentioned are all made of wood `and the upper surface thereof is suitably upholstered as shown.

.The strips 21 are spaced apart the same distance as `the slots 20 inthe panel I1 of the seat supdownwardlytherefrom are bolts 28 which project through said slots 20 and on the bottom end `of said bolts are nuts 29 and associated washers. By loosening these nuts, the seat may be adjusted forwardly or rearwardly of the support and then locked in the adjusted position by tightening up the bolt.

The ller blocks" I3l are each provided'with a` pair of bolts 3U adapted to be'extended through Anchored in` said strips rand extending certain ones of sets of vertically spaced holes I9 in the guide members I8 of the seat supporting member and to receive nuts 3| on the inner ends thereof. To adjust the seat in height, the nuts 3| are removed from the bolts 30 which are thenY moved outwardly far enough to clear the guide members |.8 of the seat supporting member shown in Fig. 4. The supporting member is then moved n upwardly or downwardly in guided relation with respect to the ller blocks I3 and guides I4 on the base into the desired elevation and .when the proper holes I9 in the guides I8 line up with the Ibolts 30, said bolts are moved inwardly andv With the substantially all-wood construction described, a strong rigid light weight chair is provided, in which the seat may be adjusted in elevation and the desired' forward or rearward position of the seat with respect to the base may be readily obtained.

While in describing the invention, we have re- `ferred in detail to the form, and arrangement of the parts described, the same is to be considered only inthe illustrative sense so that we do not wish to be limited thereto except as may be specically set forth in the appended claims.

We claim as our invention:
